A stunningly crafted, intelligent and moving horror story ... this is a subtle, revealing exposition of the power of the devil. There is an elegance to the storytelling, and a command of what evil may mean, that lingers with you long after the end
A smart, thrilling, utterly unnerving novel. Pyper's gift is that he deeply respects his readers, yet still insists on reducing them to quivering children. I like that in a writer
As compelling and smoothly chilling a tale as you'll find this year. The Demonologist shows an enormously gifted writer at the top of his game, producing a novel of eerie menace and unique depth. Those of us who write supernatural stories do not throw the names Ira Levin, William Peter Blatty, and Peter Straub around lightly. You'll be hearing all three associated with Mr Pyper soon, and all such comparisons are warranted, the highest praise I can offer
Genuinely terrifying, don't-read-late-at-night stuff. Thrilling, compelling and beautifully written
A literary horror story that values smarts over scares . . . a book about a father and daughter, and how far a parent will go to protect a child
'The Demonologist is a smart psychological thriller. Carefully crafted, claustrophobic and deeply, deeply creepy'
Milton expert Prof David Ullman finds his paradise has turned into pandemonium and the light is turning into darkness. Pyper knows how to make you afraid, very afraid.
Richly crafted, deliriously scary and compulsively page-turning from beginning to end. Imagine The Exorcist and The Da Vinci Code as penned by Daphne du Maurier. Don't miss this one!
Effective, literate, nightmarish
The Demonologist is that rare thing - a novel that is both genuinely terrifying and erudite. The research is excellent and lightly worn, the pace and cleverness of the plot thrilling, one of the most exciting works of fiction I've read for some time
The Demonologist is a scarily satisfying read
